Migration Pending version 1.9.0 self Hosted

I am trying to use the migration feature, my migration has been sitting in a "pending" state for 5 hours now?

this is all that is in the "logs"
{
"$id": "69cd392a2278dd4f2aec",
"$createdAt": "2026-04-01T15:26:34.141+00:00",
"$updatedAt": "2026-04-01T15:26:34.141+00:00",
"status": "pending",
"stage": "init",
"source": "Appwrite",
"destination": "Appwrite",
"resources": [
"user",
"team",
"membership",
"database",
"table",
"column",
"index",
"row",
"bucket",
"file",
"function",
"environment-variable",
"deployment",
"site",
"site-variable",
"site-deployment",
"provider",
"topic",
"subscriber",
"message"
],
"resourceId": "",
"statusCounters": [],
"resourceData": [],
"errors": [],
"options": []
}

you're migrating from appwrite to appwrite. what version to what version?

From 1.8.1 to 1.9.0 so I started migration proccess on newly installed 1.9.0
I just created second one they both stuck. How can I delete or stop them?

what do the logs in the migration worker show?

],
"resourceId": "",

}

no

the docker logs for the migration worker

[Error] Type: Exception
[Error] Message: _APP_MIGRATION_HOST is not set
[Error] File: /usr/src/code/src/Appwrite/Platform/Workers/Migrations.php
[Error] Line: 399
[Error] Type: Exception

please try adding that env var and setting it to appwrite

I did, same error:

[Error] Message: _APP_MIGRATION_HOST is not set
[Error] File: /usr/src/code/src/Appwrite/Platform/Workers/Migrations.php
[Error] Line: 399

Is the environment variable listed under the migration service in the compose file

I added it and got this:

btw, you might not be able to migrate from 1.8.1 to 1.9.0 like this because the 1.9.0 instance expects 1.9.x format, but the 1.8.1 instance will be sending in 1.8 format

Ok , thank you.

I am facing the same issue... same logs... but both my instances are on 1.9.0....
